GA Operators Performance Calculation Methods?

[Kerosene]

Thanks Bug,

As far as I know Abacus gives you a balanced field calculation for DRY and WET runways only, and a climb gradient, but no engine out escape routes.
The W&B has a nice graphical interface, tailored to the seating configuration of the individual tailnumber.
On an aircraft as the Global, you might be able to match or exceed the SID gradient in most cases, but for an aircraft not as powerful this can quickly become very limiting (such as many Citations, Legacies,...).
The lateral requirements for a SID are far greater than for an engine out flight path, therefore the SID has to account for obstacles that are much further away, resulting in high gradient requirements.
However, I'd already be happy to have this, better than nothing.
Happy Landings,
